SCOPE These specifications define the performance requirements for solvent free, epoxy resin and epoxy/PVC blend based, structural metal-to-metal adhesives as follows: WSK-M11P47-A1: Two component
4、materials to be used for production repair as well as dealer repair (see 4.1), WSK-M11P47-A2: One component material, low viscose, airless and/or ADFOSY sprayable, E-coatable, induction heat precurable, oven curing (see 4.1). WSK-M11P47-A3: One component material, pumpable, warm bead applied and ove
5、n curing (see 4.1). WSK-M11P47-A4: One component material, pumpable, cold bead or ADFOSY applied pregellable and oven curing (see 4.1). WSK-M11P47-A5: Two component material, pumpable, induction curable, cold bead for body in white application (see 4.1). WSK-M11P47-A6: One component material, pumpab
6、le, induction heat precurable, warm bead applied and oven curing (see 4.1). 2. APPLICATION These specifications were released originally to provide lifetime structural bonding for body components such as inner and outer panel (hem flange) of doors, rear door lock reinforcement, roof panel and pillar
7、, hood, deck lid etc. made from cold rolled as well as precoated steel. The materials are applicable on oiled surfaces with acceptable oil film weights (European applications limit the oil/pre-lubricant film weight to max 3 g/m, see para. 3.6). Note: Care must be taken to ensure that the local oil f
8、ilm weight in the area of the adhesive/sealer application does not exceed the critical limit. Monitoring of the film thickness, adequate storage of the part and/or cleaning of the surface prior to sealer/adhesive application is necessary to avoid critical film thickness values, which would then caus
9、e malfunction of the sealer/adhesive. ENGINEERING MATERIAL SPECIFICATION WSK-M11P47-A1/A2/A3/A4/A5/A6 Copyright 2015, Ford Global Technologies, LLC Page 2 of 11 3.
